....especially after long rides. When everything vibrates for long periods of time. Even more so on older bikes. Both my break switches were out of commission last night, good thing I checked. Rear break switch had one of two wires broken off. It is an easy fix just a matter of noticing it. Handlebar break switch, had one of the wires vibrated off so I had to take the switches off and re-solder it. Nothing complicated just a matter of noticing it again.
